The wiper motor is responsible for powering the windshield wipers, ensuring clear visibility during adverse weather conditions. A cracked or damaged wiper motor can lead to several problems, impacting the functionality of the windshield wipers and overall driving safety. Here are some common issues associated with a cracked wiper motor:

Non-Operational Wipers: A cracked wiper motor can cause the wipers to stop functioning altogether. Without a working motor, the wipers will not move, leaving the windshield uncleared and obstructing the driver's view during rain or snow.

Intermittent Operation: Damage to the wiper motor can result in intermittent wiper operation. The wipers may work sporadically or only in certain modes (e.g., low speed but not high speed), making it unreliable to maintain clear visibility consistently.

Slow Wiper Movement: A cracked or malfunctioning wiper motor may cause the wipers to move more slowly than usual. This can be particularly dangerous during heavy rainfall, as the wipers may not clear the windshield quickly enough to maintain adequate visibility.

Noisy Operation: A damaged wiper motor may produce unusual noises, such as grinding, whining, or clunking sounds, when the wipers are in use. These noises can indicate internal damage to the motor components, which can lead to further failure if not addressed.

Wipers Stuck in One Position: A cracked wiper motor may cause the wipers to get stuck in one position, either fully up, fully down, or anywhere in between. This can obstruct the driver's view and create a safety hazard.

Electrical Issues: A cracked wiper motor can lead to electrical problems, such as blown fuses or short circuits. This can affect not only the wiper system but potentially other electrical systems in the vehicle as well.

Inconsistent Speed Settings: If the wiper motor is damaged, it may not respond correctly to changes in speed settings. The wipers may fail to speed up or slow down when the driver adjusts the wiper control, reducing the effectiveness of the wipers under varying weather conditions.

Motor Overheating: A cracked wiper motor may lead to overheating due to internal friction or electrical issues. Overheating can further damage the motor and cause it to fail completely.

Water Ingress: A crack in the wiper motor housing can allow water to enter the motor, especially during rain. Water ingress can cause short circuits, corrosion, and further damage to the motor's internal components.

Increased Wear and Tear: A damaged motor can cause uneven or increased wear and tear on the wiper linkage and blades. This can lead to premature failure of these components and additional repair costs.

In summary, problems with a cracked wiper motor can include non-operational wipers, intermittent operation, slow wiper movement, noisy operation, wipers stuck in one position, electrical issues, inconsistent speed settings, motor overheating, water ingress, and increased wear and tear on related components. Addressing issues with the wiper motor promptly is crucial for maintaining clear visibility and ensuring safe driving conditions. If a cracked wiper motor is suspected, it should be inspected and replaced by a qualified technician.
